macvlan: Support bonding events
Bonding and team drivers generate specific events during failover that trigger switch updates. When a macvlan device is configured on top of bonding, we want switches to learn about the macvlan devices as well. This patch adds a handler to macvlan driver to propagate these events to all macvlan devices. We let the generic inetdev event handler do the work. This allows macvlan to operated correctly over active-backup mode bond. Signed-off-by: Vlad Yasevich <vyasevic@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
